Karan Johar is returning this week to woo the box office with a romantic comedy which coincides with the Valentine’s Day revelries. He has teamed up with the fresh pair of Imran Khan and Kareena Kapoor to attract the audiences.Directed by debutant Shakun Batra, the film’s cast has Boman Irani, Ratna Pathak Shah and Ram Kapoor and it will be released on 1,200 screens worldwide. It is made at an approximate budget of Rs.25-30 crore.In “Jaane Tu… Ya Jaane Na”, Ratna had played Imran’s mother, but her character in the new film is a complete contrast. In the film, Rahul Kapoor (Imran), an architect in Vegas, loses his job, but doesn’t share the bad news with his parents and secretly starts the job hunt. His life takes a turn when Riana Braganza (Kareena), a quick-witted hairstylist, enters his life.They meet and after a fun-filled night of debauchery, Rahul and Ria wake up to discover they’ve got married. They decide to annul their marriage, but in the course of next 10 days they stay together, fight, laugh and end up developing an unlikely friendship which eventually turns into love. The film was earlier titled “Short-Term Shaadi”, but later changed to “Ek Main Aur Ekk Tu”. Going by the promos, the film seems to be targetted towards younger audiences.Extensively shot in Las Vegas, the entire cast and crew enjoyed working there as the shooting schedule coincided with the festive season of Christmas and New Year celebrations.Some parts of the film have also been shot in Pataudi, Haryana.While shooting for the film, Imran also turned a photographer and clicked Kareena. Later, an exhibition was held where all those photographs were put on display.There were reports that the film’s story is similar to that of Cameron Diaz and Ashton Kutcher-starrer “What Happens In Vegas”, but the producer denies this contending that the fact that they get married in Vegas is only an aspect of the movie and not the entire movie. The story is different.The peppy and fun-filled songs of the film composed by Amit Trivedi are already a rage among youngsters and are being frequently played on radio stations.After the success of Dharma Productions’ “Agneepath”, expectations are high from the romantic comedy which is also produced by the same banner.
